CLAIMS

WHAT IS CLAIMED IS:

1. A method for wireless communication at a User Equipment (UE), comprising:

communicating, based on a first subscription, with a first Radio Access Technology (RAT) over a bandwidth part (BWP) in a set of one or more configured BWPs;

tuning a transceiver away from the BWP to a second frequency to communicate, based on a second subscription, with a second RAT for a period of time;

tuning, after the period of time, the transceiver back to a selected BWP to communicate with the first RAT;

determining that the set of one or more configured BWPs includes multiple BWPs; and

sending, based on the tuning the transceiver back to the selected BWP and on determining that the set of one or more configured BWPs includes multiple BWPs, a scheduling request to the first RAT over the selected BWP to request a scheduling grant from the first RAT.

2. The method of claim 1, wherein sending the scheduling request is further based at least in part on determining that an inactivity timer for the BWP is enabled and is configured to be larger than a wait duration for the BWP.

3. The method of claim 1, wherein sending the scheduling request comprises sending a number of scheduling requests to request the scheduling grant, wherein each of the number of scheduling requests is sent based on determining that a response is not received within one or more threshold time periods.

4. The method of claim 3, further comprising:

determining, based on sending the number of scheduling requests without receiving the response within the one or more threshold time periods, an ordering of the set of one or more configured BWPs; and

for at least a first BWP in the ordering of the set of one or more configured BWPs, sending a subsequent scheduling request to the first RAT over at least the first BWP to request the scheduling grant from the first RAT.

5. The method of claim 4, further comprising for at least a second BWP in the ordering of the set of one or more configured BWPs that is next in order following at least the first BWP, and based on not receiving the scheduling grant in response to the subsequent scheduling request, sending a second subsequent scheduling request to the first RAT over at least the second BWP to request the scheduling grant from the first RAT.

6. The method of claim 4, wherein sending the subsequent scheduling request comprises sending a number of subsequent scheduling requests to request the scheduling grant, wherein each of the number of subsequent scheduling requests is sent based on determining that a response is not received within one or more subsequent threshold time periods.

7. The method of claim 6, further comprising:

tuning, based on sending the number of subsequent scheduling requests for each BWP in the ordering of the set of one or more configured BWPs without receiving the response within the one or more subsequent threshold time periods, to a configured default BWP; and

initiating a random access channel (RACH) procedure with the first RAT over the configured default BWP.

8. The method of claim 4, wherein the one or more threshold time periods include an inactivity timer for the BWP, a wait duration for the BWP, and an upper time limit since tuning back from the second RAT.

9. The method of claim 4, wherein determining the ordering of the set of one or more configured BWPs comprises determining the ordering based on determining an activity level or last usage for each BWP in the set of one or more configured BWPs.

10. The method of claim 1, further comprising maintaining an inactivity timer for the BWP while the transceiver is tuned to the second frequency.

11. The method of claim 10, wherein maintaining the inactivity timer comprises adjusting the inactivity timer based on an elapsed time after the transceiver is tuned back to the BWP.

12. A method for wireless communication at a UE, comprising:

communicating, based on a first subscription, with a first Radio Access

Technology (RAT) over a bandwidth part (BWP) in a set of one or more configured BWPs;

determining to switch to a different BWP in the set of one or more configured

BWPs;

tuning, before switching to the different BWP, a transceiver away from the BWP to a second frequency to communicate, based on a second subscription, with a second RAT for a period of time; and

tuning, after the period of time, the transceiver to the different BWP to communicate with the first RAT.

13. The method of claim 12, wherein determining to switch to the different BWP comprises determining to switch to a default BWP where an inactivity timer expires before or during tuning the transceiver away from the BWP.

14. The method of claim 12, wherein determining to switch to the different BWP comprises receiving an indication to switch to the different BWP before tuning the transceiver away from the BWP.

15. The method of claim 14, further comprising initializing an inactivity timer before tuning the transceiver away from the BWP.

16. The method of claim 15, wherein tuning the transceiver to the different BWP comprises determining to switch to a default BWP where the inactivity timer expires before or during tuning the transceiver away from the BWP.

17. The method of claim 15, wherein tuning the transceiver to the different BWP is based at least in part on determining that the inactivity timer did not expire.

18. An apparatus for wireless communication, comprising:

a transceiver;

a memory configured to store instructions; and

one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:

communicate, based on a first subscription, with a first Radio Access Technology (RAT) over a bandwidth part (BWP) in a set of one or more configured BWPs;

tune a transceiver away from the BWP to a second frequency to communicate, based on a second subscription, with a second RAT for a period of time;

tune, after the period of time, the transceiver back to a selected BWP to communicate with the first RAT;

determine that the set of one or more configured BWPs includes multiple BWPs; and

send, based on the tuning the transceiver back to the selected BWP and on determining that the set of one or more configured BWPs includes multiple BWPs, a scheduling request to the first RAT over the selected BWP to request a scheduling grant from the first RAT.

19. The apparatus of claim 18, wherein the one or more processors are configured to send the scheduling request further based at least in part on determining that an inactivity timer for the BWP is enabled and is configured to be larger than a wait duration for the BWP.

20. The apparatus of claim 18, wherein the one or more processors are configured to send a number of scheduling requests to request the scheduling grant, wherein each of the number of scheduling requests is sent based on determining that a response is not received within one or more threshold time periods.

21. The apparatus of claim 20, wherein the one or more processors are further configured to:

determine, based on sending the number of scheduling requests without receiving the response within the one or more threshold time periods, an ordering of the set of one or more configured BWPs; and

22. The apparatus of claim 21, wherein the one or more processors are configured to, for at least a second BWP in the ordering of the set of one or more configured BWPs that is next in order following at least the first BWP, and based on not receiving the scheduling grant in response to the subsequent scheduling request, send a second subsequent scheduling request to the first RAT over at least the second BWP to request the scheduling grant from the first RAT.

23. The apparatus of claim 21, wherein the one or more processors are configured to send a number of subsequent scheduling requests to request the scheduling grant, wherein each of the number of subsequent scheduling requests is sent based on determining that a response is not received within one or more subsequent threshold time periods.
